When I was studying the Holocaust 2 facts that I learned  is that, Collaborators killed about 6 million jews.Also I learned that in the Holocaust there were many parts to it. Collaborators are like Nazis, but did so much worse things. They committed some of the worst atrocities in Holocaust history.  What I will keep with me forever is I will never do  something to  Physically hurt someone else. 

Another lesson that I learned for the holocaust was WWII in Europe. The Germans invaded so many countries. They did not care who they hurt in the process of the war. They were basically out to kill the Jewish people. What I learned from this is that if I hurt somebody, I will apologizes and help them get back up.
